Have you run HiJackThis and used the log file analyser from Eddy’s site? I strongly doubt it, HiJackThis is the best tool for removing items in the registry and this sounds like something is kicking this off (running at 10:37) and that is likely to be a registry entry.
Have you tried scheduling a boot-time scan?
Did you try finding ncase removal tools/advice using google? This is just one of many I found http://www.pchell.com/support/ncase.shtml, google is your friend learn to use the tools. Would you care to guess what they are doing to remove this, yes, editing the registry. This is what HiJackThis does without you having to do it manually!
